Slant/Fin Overheating Components / Electrical Overload

Boiler operates but emits a metallic or burning smell

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Overheating circulator motor, Loose electrical connections on Slant/Fin boiler, Insulation contacting hot surfaces, Failing transformer

Safety: If you smell burning plastic or insulation, turn off power immediately.

Steps:

1. Visual inspection: Look for discolored wiring, melted insulation, or scorched areas on the control board and junction box.
2. Motor temperature: Carefully touch the circulator and inducer motors; they should be hot but not too hot to touch briefly. Excessive heat suggests overload.

Professional repair: Electrical overheating requires a technician to test current draw, tighten connections, and replace failing components.
